Reaction Bonded Silicon Carbide Grinding Barrel Introduction

Silicon carbide ceramic sand mill inner barrel with light weight,high hardness,crossion resistance,high temperature resistance and other properties.It's better than traditional zirconia ceramics in resistance to erosion and wear(low abrasion value can prevent material from pollution).The coefficient of thermal conductivity is 130 W/m.k(20℃),it is the best cooling effect ceramic material which has the advantages to control the temperature rise in the process of equipment operation.

The barrel is through the casting or isostatic pressing molding forming technology,can be effective isolation lumen and outer shell,make it is not subject to corrosion and scouring.Service life is 5 to 10 times of general wear-resisting material,integrated operation cost is low.
